I purchased this from Amazon last year for around 4500 yen and have kept it stored at home without using it. It's a low-rebound mat designed to reduce the strain on your legs and lower back when standing for long periods. There is some dust accumulation from storage. This anti-fatigue mat is made of 76x50cm EVA resin with a dot texture for a non-slip effect. It's a 25mm thick kitchen mat, a fatigue-reducing standing mat, using 140D high-density, high-rebound PU foam. Ideal for standing desks in offices, kitchens, cash registers, podiums, etc. It's non-slip, waterproof, and stain-resistant, making it easy to clean. Black.
